Multiple Dungeons in Dungeon Lobby

[Celestina]

When I go into the dungeon lobby i see three question marks on the right side for me to select dungeons, so I select three i want to do. I get my party and we begin. Defeat the first dungeon and the portal doesnt change to the next one on the list. Whats wrong? How do I make it cycle to the next one? Is this a broken feature? Also is there a legit way to use the dungeon lobby to do my dailies solo?
